A small aircraft, starting from rest, makes a forward run of 24 m before lifting off. If ax = 7.3 m/s^2, Determine (a) What is the aircraft's final velocity, Vfx, at take off? (b) What is the aircraft's average velocity? (c) How long does the aircraft take to travel the 24 m?

You throw a ball vertically upward, and as it leaves your hand, its speed is 38.0 m/s. (a) How high (in m) does it rise above the level where it leaves your hand? m (b) How long (in s) does it take to reach its highest point? s (c) How long (in s) does the ball take to return to the level where it left  your hand after it reaches its highest point? s (d) Assume that the upward direction is positive and the downward direction is negative. What is the ball's velocity (in m/s) when it returns to the level where it left your hand? (Indicate the direction with the sign of your answer.) m/s

A swimmer bounces straight up from a diving board and falls feet first into a pool. She starts with a velocity of 3.00 m/s, and her takeoff point is 1.30 m above the pool.(a) How long are her feet in the air?  s(b) What is her highest point above the board?  m(c) What is her velocity when her feet hit the water?  m/s

A small mailbag is released from a helicopter that is descending steadily at 1.06 m/s. (a) After 4.00 s, what is the speed of the mailbag? m/s (b) How far is it below the helicopter? d= (c) What are your answers to parts (a) and (b) if the helicopter is rising steadily at 1.06 m/s? v= m/s

A hovercraft has an initial position of r(t = 0s) = 235m @ 265◦, an initial velocity of⃗v(t = 0s) = 125m/s @ 14◦, and a constant acceleration of ⃗a = 21.3m/s^2 @ 143◦.(a) How long does it take for the x coordinate of the hovercraft’s position to reach -100m?(b) What is the hovercraft’s position at this time?(c) What is the hovercraft’s velocity at this time?

A hoodlum throws a stone vertically downward with an initial speed of 15.0 m/s from the roof of a building, 36.0 m above the ground. (a) How long does it take the stone to reach the ground? (b) What is the speed of the stone at impact?

A swimmer bounces straight up from a diving board and falls feet first into a pool. She starts with a velocity of 4.00 m/ s, and her takeoff point is 1.80 m above the pool. (a) How long are her feet in the air? (b) What is her highest point above the board? (c) What is her velocity when her feet hit the water?

A cat falls from a tree (with zero initial velocity) at time t = 0. How far does the cat fall between t=0.3s and t = 1.4 s? Use Galileo's formula u(t) = 32t fus. Answer: ft.

You throw a ball vertically upward, and as it leaves your hand, its speed is 21.0 m/s. (a) How high (in m) does it rise above the level where it leaves your hand? m (b) How long (in s) does it take to reach Its highest point? (c) How long (in s) does the ball take to return to the level where it left your hand after it reaches its highest point? (d) Assume that the upward direction is positive and the downward direction is negative. What is the ball's velocky (in m/s) when t returns to the level where E left your hand? (Indicate the dectis with the sign of your answer.) m/s
